Easy wind tunnel testing question
Easy wind tunnel testing question
(OP)
My father always says there's no such thing as a stupid question if you dont know the answer, but today, Im feeling stupid regardless asking this question. You may have gathered I dont know much on this subject but do wonder about it.
If I have a scale model of a car, lets say 10 times smaller for arguments sake. I fix that into a wind tunnel with appropriate sensors attached.
If I want to test what drag/downforce/etc the car has at 100mph, what should my wind tunnel speed be?
10mph, 100mph, or 1000mph? I do realize 1000mph is complete madness to even type that but I just listed it as an example.
Or, do I just pick any speed and some way scale the forces then to suit real world speeds/values.
Go easy on me now...this isn't my day job...(lucky for all)
Thanks

Im not doing anything with this, I just want to have a basic understanding,
